PEO vs. Administrative Services Organization (ASO)
Unlike ASOs, which simply handle HR but don't take on any additional employer responsibilities , PEOs adopt a co-employment model that makes them the employer of record . Both do provide HR services, but in different ways.
Feature | PEO | ASO |
---|---|---|
Employment Model | Co-employment arrangement | No co-employment |
Employer of Record | Yes | No |
Payroll taxes & Compliance | Managed by PEO | Managed by client |
Employee Benefits Access | Large-group plans | Client's own plans |
An ASO can be a good choice for companies wanting HR assistance without changing the employment relationship , but a PEO offers broader compliance coverage and access to enterprise-level benefits.
PEO vs. Traditional HR Outsourcing
A professional employer organization provides a full suite of HR services to small businesses and medium-sized companies through a co-employment model, in which the PEO is the employer of record for the employees as far as, for instance, payroll processing , employee benefits , risk management , and regulatory compliance are concerned. The structure offers small businesses access to enterprise-level resources and large group benefit plans.
Classic or Traditional HR outsourcing does a specific human resource function such as recruiting or benefits administration . Unlike professional employer organizations (PEOs), they don't take on any employer responsibilities . Also, they do not take on any liability for compliance. Though this choice might fit businesses in search of precise assistance, it won't provide the all-in-one integration or compliance coverage offered by a PEO.
PEO vs Staffing Companies
A professional employer organization enters into a long-term co-employment relationship with the client company in which it controls payroll taxes , employee benefits and regulatory compliance but the client company maintains operational control. In contrast, staffing companies provide independent contractors and temporary workers for short-term use only. They do not provide benefits administration or any employer responsibilities .

PEO vs. In-House HR Departments
A PEO provides scalable HR solutions that often cost less than maintaining an entire in-house human resource department. A PEO gives you big company capabilities without the expense of adding staff by managing payroll processing , employee benefits , risk management , and regulatory compliance .
On the other hand, in-house HR teams provide companies with direct control over their processes. But they also require a serious investment in salaries, training and technology.
